[BUG] Offset Information cleared/error after unmounting device/platform

Hi,

If I unmount a device, the information of the entered offsets is deleted. I tried two different things:

1. Mount and unmount [images 1+2] of a device with specified z-offset value. After unmounting the device, z-offset = 0

2. Mount and unmount [images 3+4] of a device with x-offset, y-offset and z-offset values ​​specified. After unmounting the device, z-offset = 0.1. In this example, this corresponds to the entered x-value. It seems as if the save process uses the entered value from this field for all other fields.
